This sounds like a homework assignment. If it is, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.

If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the free MATLAB Onramp tutorial to quickly learn the essentials of MATLAB.

If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.

prompt = "What is the original value? ";

x = input (prompt);

y = x+d/2;

disp(y)

>> Calculator

Error using input

The first argument to INPUT must be a character vector.

Error in Calculator (line 2)

x = input (prompt);

Hi,

For a basic calculator, you can take the 3 numeric inputs using the input function, perform the necessary operations, and then print the value using the disp function, if required.

To learn more about the input and disp function, please refer to the MathWorks documentation below:
